It has been two months since health officials discovered a new strain of the coronavirus – a strain responsible for the deaths of over 3,000 people and that has sickened tens of thousands around the world.
Human coronaviruses are not new. They were first characterized in the 1960s. The virus causes respiratory tract infections, with symptoms similar to the common cold.
Dec. 31, 2019
The first cases of what was thought to be pneumonia were reported to the World Health Organization. It is believed that animals sold at the quickly closed Huanan Market in Wuhan, China were the source. Within a week, it is confirmed that the Chinese patients have the novel coronavirus. The WHO labels it COVID-19 or Coronavirus Disease 19.
